Title: Improvements in or relating to compositions comprising vinyl chloride polymers or copolymer resins
IPC: C08K5/57
Filed: 1952-03-28
Abstract: Compositions comprising vinyl chloride polymers, e.g. vinyl chloride-vinyl acetate copolymer, are stabilized against heat and light by incorporating therein an organometallic tin salt of a carboxylic acid and a phosphate, carbonate or silicate of magnesium. Specified organo-metallic tin salts are dibutyl tin diacetate, dioleate and dilaurate, diphenyl tin distearate, dibutyl tin maleate and fumarate and tri- (dibutyl tin) diaconitate.  The magnesium salt, which may have a refractive index equal to the vinyl chloride polymer, may be trimagnesium phosphate, magnesium orthophosphate, basic magnesium carbonate, hydrous magnesium carbonate, magnesium silicate or sepiolite.  The compositions may also contain plasticizers, e.g. dioctyl phthalate, lubricants, e.g. stearic acid, pigments and fillers.

Title: High resolution pulse-echo ultrasonic imaging display system
IPC: G01S7/52
Filed: 1976-03-04
Abstract: To generate a visible image of an optically opaque, spatially extended structure, for example a part of the interior of a human body, this is "illuminated" with a beam emitted by an ultrasonic unit (206) and focused by an acoustic lens (202). The intensities of the rays reflected by the structure and projected back to the ultrasonic unit (206) by the lens (202) are evaluated by imaging electronics to form an image of the structure examined, which appears on a display device (220). To image the spatially extended structure, discrete points (210) thereof are individually scanned. This is done by deflecting an inertialess beam (204) emitted by the ultrasonic unit (206). To deflect the beam, mechano-electronic or exclusively electronic means are used which operate at such a high scanning rate that real-time reproduction with good resolution is possible. <IMAGE>

As shown, when the lid 1 to the cigarettecontaining part of the case is closed, a spring tongue thereon presses on a stud 18 on a spring 16 in the other part of the case and releases the spring from a catch 17 on the hood 7. Springs 21 push the hood outwards and a hooked lever 14 pivoted to the hood engages a stud on the flint wheel 13 and rotates the latter to ignite the wick 12 in the usual manner. The spring in the lid 1 has an enlarged head which slips past the stud 18 without moving it when the lid 1 is opened. The fuel container of the lighter is filled with absorbent material which is replenished with fuel through a screw stopper 20. A metal strip &c. adjacent the spring 16 prevents fumes from the lighter from entering the other part of the case.

Abstract: 564,946. Luminescent materials. COLE, Ltd., E. K., and EVANS, J. N. I. June 3, 1943, No. 8889. [Class 39 (i)] A fluorescent material formed of intimately mixed magnesium or zinc tungstate and magnesium or zinc silicate is formed by heating magnesium or zinc oxide, or substances that yield these oxides on heating, with tungstic oxide, the former being in excess of that required to combine with the tungstic oxide, and sufficient silica is included in the mixture to combine with all this excess to form magnesium or zinc silicate. The silica is obtained in a fine state of sub-division by precipitation from a mixture of sodium disilicate and sodium chloride solution with an ammonium chloride, nitric acid solution. In an example, magnesiumoxide, tungstic oxide and silica are ground in a ball mill with the addition of some distilled water, dried at 150‹ C. for four hours, and then fired at 1,120‹ C. for three to four hours. Any free magnesium oxide left may be extracted by boiling with an ammonium chloride solution. Zinc beryllium silicate may be added to the material for colour modification.
